A conclusive date of cultural beginnings has always evaded the archaeologist. Here, provenience and preservation are key concerns and are dependent upon the movement, interference and environmental conditions surrounding the artifact or site. It is important to remember that cultures presenting an abundance of material remains are by no means representative of the most advanced, or ‘developed’ cultural groups; cultures that lack material remains may have functioned under a technologically rich social organization. Many of the latter may be seen in Southeast Asia’s archaeological record. Artifacts constructed of perishable materials such as bamboo, wood and bone have long since decomposed, leaving the archaeological record with pottery, stone implements and in later times monumental architecture and an advanced bronze industry.
